Reconstituted Complex
An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.

RNPS1 is modulated by ubiquitin-specific protease 4.
RNA-binding protein with serine-rich domain 1 (RNPS1) is a component of pre-splicing and post-splicing multiprotein complexes, which activates constitutive and alternative splicing. RNPS1 participates in the formation of the spliceosome and activates the pre-mRNA splicing process. In the present study, we found that ubiquitin-specific protease 4 (USP4) is a binding partner of RNPS1. Although RNPS1 is polyubiquitinated by both K48- ... [more]

| USP4 RNPS1 | Affinity Capture-Western Affinity Capture-Western An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins. | Low | - | BioGRID | - | |
